Invitrogen™ FceR1 alpha Monoclonal Antibody (CRA2 (AER24)), Biotin

Mouse Monoclonal Antibody

Supplier:  Invitrogen™ MA14999

Catalog No. PIMA14999

Description

MA1-4999 detects Fc epsilonR1 alpha (Biotin) from human samples. The CRA2 (AER24) monoclonal antibody reacts with the Fc epsilonR1 alpha subunit on a region that overlaps the region of the IgE binding site, thus it competes with IgE for the receptor bindi MA1-4999 has been successfully used in Western blot, flow cytometry, and immunohistochemistry applications. The MA1-4999 immunogen is region of Fc epsilonR1 alpha which overlaps with the IgE binding site; Swiss protein P12319. The epitope has been mapped to amino acids 110-197.

Fc epsilon RI alpha, also known as FceR1 alpha, is a subunit of the high-affinity receptor for IgE, primarily expressed on mast cells and basophils. Its expression is upregulated by the presence of IgE. Fc epsilon RI alpha forms a tetrameric complex with one beta and two gamma subunits, which are essential for signal transduction. The beta and gamma subunits contain immunoreceptor tyrosine-based activation motifs (ITAMs). The Fc epsilon RI complex plays a crucial role in triggering IgE-mediated allergic reactions. When allergen-bound IgE molecules bring together two or more high-affinity IgE receptors, it leads to the release of mediators such as histamine, which are responsible for allergy symptoms. This process couples allergens and mast cells to initiate inflammatory responses characteristic of allergic disorders like hay fever and asthma. The release of histamine and proteases also leads to the synthesis of prostaglandins and leukotrienes, which are potent effectors of the hypersensitivity response.
